in the nw, most "cool" folks hated this stuff. it was like the crap that was sold to the tourists. among "artists" up there, if you said, "oh, i do nw indian stuff", it was like the kiss of death in hippie-kitsch form.
i suspect that joe was making a little joke when he did this poster...
who printed these cheapo offset quickprint things? i miss that stuff - especially with the cheapo split fountain tossed in. back in the 1980's all posters were printed this way. $35 for anywhere from 50 -300 11x17 posters. color was optional. cheap, happy.
he did this about 1983-84. flex lenses had just entered the market (for stat cameras) in seattle, so he had some type set and then pasted them up all wonky on a sheet, then had it flexed one way, then the other. then he cut them up and made the words he needed.
he used 3-d colors, so when you put on the 3d glasses, it gave you a headache.
